As shown in the figure, the baby carriage brake mechanism includes a pair of brake hubs 11, a pair of pedal parts 12, a pair of bases 13, a pair of wheel fixing seats 14, a pair of elastic parts 15, a wheel shaft 16 and a linkage tube 17. The wheel shaft 16 is installed between a pair of baby carriage wheels 20, the pair of brake hubs 11 are fixed on the inner side of the corresponding baby carriage wheel 20, and the pair of pedal members 12 are sleeved on the wheel shaft 16 and connected to the wheel shaft 16. The pair of brake hubs 11 correspond to each other, and the pair of bases 13 are correspondingly accommodated in the pair of pedals 12 . The pair of wheel fixing seats 14 and the pair of elastic members 15 are correspondingly accommodated in the base 13, and the two ends of the axle 16 pass through the pair of pedal members 12 and the pair of bases 13 in turn, Eventually insert the stroller wheels 20 on both sides. The linkage pipe 17 is sheathed on the wheel shaft 16 , and two ends of the linkage pipe 17 are respectively connected to the pair of footrests 12 . In the present invention, because the structures of the parts of the baby carriage braking mechanism respectively installed on the pair of baby carriage wheels 20 are completely consistent, so the present embodiment only applies to the baby carriage braking mechanism mounted on one side of the baby carriage wheel 20. parts are described.

Specifically, as shown in Figure 2a and Figure 2b, the brake hub 11 is fixed on the inner side of the stroller wheel 20, and the brake hub 11 is provided with a plurality of projections 111 surrounding the wheel shaft 16 and distributed at intervals, corresponding to A plurality of engaging grooves 112 are formed between adjacent protrusions 111 . Correspondingly, as shown in FIG. 4 , one side of the tread member 12 protrudes toward the brake hub 11 to form a brake rib 121 . When it is necessary to brake, step on the pedal member 12, and the pedal member 12 will rotate, so that the brake rib 121 snaps into the draw-in groove 112 to achieve braking; and when the brake needs to be released, the user Only need to lift up the footrest 12, the footrest 12 rotates, the brake rib 121 can be disengaged from the locking groove 112, so as to release the brake. The baby carriage brake mechanism has a simple structure, and the matching relationship between the brake ribs 121 and the locking groove 112 is also relatively simple, and the cost is low.

Referring again to FIG. 2 a , FIG. 2 b and FIG. 4 , both sides of the pedal member 12 are provided with limiting holes 122 and first installation holes 123 . In another embodiment of the present invention, a limiting hole 122 is provided on one side of the pedal member 12 . Part of the edge of the limiting hole 122 protrudes into the limiting hole 122 to form a tongue 124, and the tongue 124 divides the limiting hole 122 into a first sub-limiting hole 122a and a second sub-limiting hole 122a. Limiting hole 122b. Preferably, the tongue 124 is an elastic piece. Correspondingly, both sides of the base 13 are provided with limiting protrusions 131 and second mounting holes 132 . When the base 13 is accommodated in the pedal member 12 , the limiting protrusion 131 is inserted into the limiting hole 122 . The wheel fixing base 14 is provided with a third mounting hole 141, the third mounting hole 141, the second mounting hole 132 are aligned with the first mounting hole 123, and a connecting piece 18 (such as a rivet) passes through in sequence The first mounting hole 123 , the second mounting hole 132 and the third mounting hole 141 are used to realize the connection between the wheel fixing seat 14 , the base 13 and the footrest 12 . Since the tongue 124 is an elastic piece, when the footrest 12 is stepped on or lifted, the limiting projection 131 interferes with the tongue 124 to deform, so that the projection 131 can be positioned at the The movement between the first sub-limiting hole 122a and the second sub-limiting hole 122b is achieved, so as to realize the limitation and positioning of the rotation stroke of the pedal member 12 . When the pedal member 12 is at the braking position, that is, the brake rib 121 snaps into the card slot 112, and the protrusion 131 is located in the first sub-limiting hole 122a; when the pedal member 12 When it is in the unlocking position, that is, the brake rib 121 is separated from the engaging groove 112, and the protrusion 131 is located in the second sub-limiting hole 122b. It should be noted that, in another preferred embodiment of the present invention, the position-limiting protrusion 131 is disposed on the pedal member 12, and the position-limiting hole 122 is disposed on the base 13, which can also reach Same limit function.

It should be noted that the baby carriage brake mechanism of the present invention can also realize the function of double brakes with one step. Specifically, as shown in Figure 1 and Figure 2a, the linkage tube 17 is sheathed on the wheel shaft 16, and at least one slot 171 is provided at both ends of the linkage tube 17, and the legs on both sides At least one locking portion 125 is disposed on the step member 12 . After the baby carriage brake mechanism is assembled, the clamping portions 125 of the footrests 12 on both sides are correspondingly inserted into the slots 171 on the linkage tube 17 . Therefore, when one of the pedal members 12 is stepped on, the rotation of the pedal member 12 will drive the linkage tube 17 to rotate, thereby driving the pedal member 12 connected to the other end of the linkage tube 17 to rotate. , to achieve the brake at the other end, and then realize the function of one step and two brakes.

Referring to FIG. 2 a and FIG. 3 , one end of the elastic member 15 is in contact with the base 13 , and the other end is in contact with the wheel fixing seat 14 . Specifically, a convex rib 133 protrudes from the inside of the base 13 , and when the baby carriage brake mechanism is assembled, one end of the elastic member 15 abuts against the convex rib 133 . With such an arrangement, when the baby carriage brake mechanism encounters a collision, the elastic member 15 can play a certain shock-absorbing effect.

As shown in FIG. 5 , an embodiment of the baby carriage of the present invention includes a vehicle frame 30 , a pair of baby carriage wheels 20 and a baby carriage brake mechanism 100 , and the baby carriage wheels 20 and the baby carriage brake mechanism 100 are both connected to the vehicle frame 30 . The baby carriage braking mechanism 100 has been described in detail in the above embodiments, and it can be applied to different vehicle frames 30 and baby carriage wheels 20 , and will not be repeated here.
